Answer 3

make sure all the air is purged from the system.remove the radiator cap,.run the car with heater on hot with the fan on high.let run till air is purged and the fans under the hood have cycled.you should also have a little purge valve on the top of the motor at the top hose,its a 10mm bolt.loosen it till just antifreeze comes out.
